Keto Cornstarch Substitute For Frying

Cornstarch is one of the culinary ingredients that I have come across that is extremely versatile; having it in your kitchen would be beneficial in many recipes. It may seem like a basic whitish powder, but it helps watery sauces get thicker, makes baked goods tender and chewy, makes omelets fluffy, and many other fried foods crispy and crunchy.

Apart from culinary uses, it also has other industrial uses like making adhesives, textile manufacturing, etc. Cornstarch is a great ingredient, yet it is not the best addition in keto-friendly recipes, which is why this article aims at discussing the other keto-friendly cornstarch substitute that can be used in many recipes, especially fried ones.

Keto Cornstarch Substitute For Frying

What is Cornstarch?

Cornstarch is a whitish starch powder from the crushed endosperm of corn; it is rich in carbohydrates and extremely useful in both culinary and non-culinary.

Cornstarch was invented in 1842 by staff in a wheat starch factory in New Jersey known as Thomas Kingsford. The use of Cornstarch today as a cooking ingredient was not the main intention of Thomas when he made Cornstarch, he planned for it to be used in laundry as starch, but it turned out that Cornstarch was far more useful than industrial purposes.

Cornstarch is easily modifiable and has industrial uses like baby powders, adhesives, bioplastics, etc. It is also used in medical therapy and produces medical products like surgical gloves, condoms, diaphragms, etc.

Cornstarch also carries properties that aid people with glycogen storage disease by enabling the supply of glucose to maintain blood sugar levels.

Cornstarch Uses in Recipes

The good thing about Cornstarch is how it produces great results whichever way you cook it, whether you choose to bake with it, boil it in soups and sauces, or fry with it.

It gives a tender and chewy texture to many baked goods like Cookies, shortbread, etc.

For thickening soups, sauces, custards, and many other liquid-based recipes, Cornstarch is mixed first in cold water and added to the boiling recipe; it becomes transparent and leaves no trace in the recipe, yet it gives a fine thick texture to the meal.

Another great way to use Cornstarch is in fried recipes; chicken is a perfect example. When using Cornstarch, a thin layer of Cornstarch is used to coat the outer layer of chicken which helps in giving it that crispy texture when fried.

Cornstarch is utilized in a lot of recipes, and some of them include:

Cornstarch is made up primarily of corn endosperm, which is rich in starch( a carbohydrate), and nutritious starchy foods provide the body with energy, fiber, vitamins, and minerals which aids digestion, satiety, and energy levels.

However, since Cornstarch contains starch, it is not the best option for people with diabetes or on a keto- diet, so a substitute is important.

There are several alternatives for Cornstarch that are keto-friendly and can perform the roles of Cornstarch in many recipes, including the fried ones.

In this article, we will be discussing some keto-friendly substitutes for Cornstarch when frying.
